Coronode connection arrangement

Abstract

A corona discharge device having a coronode of the type including a wire electrode coated with a fractureable dielectric sleeve for example, glass. Electrical contact is made to the wire via a conductive member forcibly attached or crimped to the sleeve to fracture it sufficiently to permit direct contact between the wire and the member.

What is claimed is: 
     
       1. A corona discharge device comprising a coronode, said coronode including an inner wire coated with a frangible dielectric and a conductive member carried on at least one end of said coronode, said member fracturing said dielectric material to contact said inner wire. 
     
     
       2. The combination recited in claim 1 wherein said member comprises a metal sphere having a groove formed therein to straddle said coronode. 
     
     
       3. The combination recited in claim 1 wherein said dielectric is glass. 
     
     
       4. The combination recited in claim 3 wherein said member comprises a metal sphere having a groove formed therein to straddle said coronode. 
     
     
       5. The method of making electrical contact to a elongated wire coated with a frangible dielectric comprising the steps of partly surrounding said dielectric with a conductive compressible member, and   applying a force to said member to compress it onto said dielectric and fracture said dielectric to result in direct contact between said member and said wire.
